A spherical bass has a diameter of 1.00 inch and a mass of 2.00 grams. Will the ball float or sink water? Remember that if the ball's density if greater than 1.00 g/mL the density of water, the ball will sink. Also remember to use dimensional analysis.

Answer 1

Convert 1" to cm
1 in x 2.54 cm/in = 2.54 cm
Volume sphere = (4/3)*pi*r^3
Then density = mass/volume = ? and compare with 1.00 g/cc.

Answer 2

This would be the correct answer I was looking for.

Mass 2.00 Grams
Volume sphere = (4/3)*pi*r^3

Find radius first

1.00/2= 0.500in/2.54cm/1in ( the inches cancels out your left with 1.27 cm as the radius.

Volume of a sphere
(4/3)(3.14)(1.27)^3=8.58

Density = 2.00g/8.58cm^3= 0.233 g/cm^3

Ans 0.233 g/cm^3(its okay a lot of people make this mistake all the time not converting there units). your welcome.
